Dirt is a multi-platform IRC proxy that adds FiSH-compatible chat encryption (including DH1080 key exchanges) to any IRC client. It can be used as a SOCKS proxy or as a simple bouncer. For security reasons, only localhost connections are allowed.

libjmmcg is a basic, low-level library with pretensions to implementing features above and beyond (but not necessarily better than!) those implemented within the Standard C++ Library and the Boost Library. It features a library for multi-core or multi-chip SMP parallelism, a suite of hashing algorithms, functions for raising numbers to integer powers, a generic factory wrapper and a generic, multi-threaded, read-only cache (which uses PPD), arguably the world's worst sorting technique, trace output, exceptions that have the file, line, revision, function, and argument details, string utilities, logging, simple command line processing, and much more.

Awlsim is a Step 7 AWL/STL/PLC simulator. Depending on the host machine and the Python interpreter used, it achieves good performance of several thousand to millions of AWL/STL instructions per second. S7-300 and S7-400 CPUs (with 2 and 4 accus) are supported.

Galera wsrep provider is a dlopenable generic replication library which implements the wsrep provider API. It provides very efficient synchronous replication, and multi-master and "parallel applying" capabilities for opaque data buffers. Its primary focus is data consistency. A transaction is either committed on every node, or not at all. It works anywhere TCP works, including on WAN, and can utilize UDP multicast where available. It is used by the MySQL-wsrep patch project to create true multi-master MySQL/InnoDB clusters.

ReplicaNet is an object oriented C++ library for developers of applications that require a stable and low maintenance middleware solution to networking. Any project that is designed to use a network of machines, such as multiplayer computer games, need to very carefully consider how to approach the design problems associated with networking. It includes support for binary difference patch creation and delivery, backend availability and TitleID verification, Internet CD/license key verification, NAT detection, advertising and querying of sessions, user accounts, friends lists, game invites, chat rooms, persistent data storage, and statistics and ranking.

propertypp adds Objective-C-like properties to C++ classes. Reading and writing properties uses the same syntax as reading and writing public member variables, but getters and setters get called behind the scenes.

Subs is a Scheme Lisp interpreter written in C++. The implementation is incomplete and naive, but aims to implement enough to be able to run every code sample in Structure and Interpretation of Computer Programs.

Crack is a programming language that aims to provide the ease of development of a scripting language with the performance of a compiled language. The "crack" program is a "script executor" that compiles source
to machine code on the fly, though it will cache the code to intermediate formats as appropriate. The crack language itself derives concepts from C++, Java, and Python, incorporating object-oriented programming, operator overloading, and strong typing.

nedtries is a portable in-place bitwise binary Fredkin trie algorithm that allows for near constant time insertions, deletions, finds, closest fit finds, and iteration. It is approximately 50-100% faster than red-black trees and up to 20% faster than O(1) hash tables. It provides implementations as C macros, C++ templates, and as a C++ STL compatible associative container.
